Stouder,Ardmore, one. Application'lti arch 15, 1935, Serial No. 11,305 l 2Claims. (cl. 261-91) This invention relates to an air conditioner bymeans ofwhich air may be cleaned andcooled.

One ,object of the invention is to provide a device of this character ofsuch construction that it may 5 be readily transported from-one part ofa room or building to another and thus air in all portions of a largeroom conditioned, or the air in a number of rooms successively treated.

Another object of theinvention is to so form the conditioner that whenit is in use, air will be drawn through an inletinto the body lportionofthe device where itwill be passed through a spray of fine waterparticles before passing out of the device and thus dust and otherforeign matter removed from the air and also the temperature 01' the airreduced by contact with the water spray. Another object of the inventionis to retard outward movement 01' the air from the body by contact witha plurality of baflies whichalso serve as stop's against wln'ch moisturein the outgoing air will catch and be prevented from passing out withthe cleaned and cooled air.

Another object of the invention is to provide improved means torcontrolling the path of move- 5 ment of the airas it passes from theconditioner and cause the blast of cleaned and cooledair to bedistributed throughout a room. r

Another object of theinvention is to provide improved means for takingup water from the lower portion of the conditioner and causing thiswater to be thrown upwardly in a very fine spray or fog through whichthe air passes and to further so mount the water sprayer that a sump maybe providedbeneath' it wherein dirt in the'water will collect andthusmake frequent changing of the water not necessary.

The improved air conditioner is illustrated in the accompanyingdrawings, wherein Figure 1 is a'view showing the improved condi- 40tioner' in front elevation with portions broken away. a s

Figure 2 is a sectional view taken vertically through the conditioner.

Figure 3 is a sectional view taken transversely through the upper.portion of the conditioner along the line 3 3 of Figure 2. y

'Figure 4 is a transverse sectional view taken through the lower portionof the conditioner along the line 4 -4 of Figure 2. Figure 5 is anenlarged view line 55 of Figure 2. z i This improved air conditioner hasa body portion consisting of a casing which extends vertically and hasvan upper ,section I, the lower end of which telescopes into thecylindrical neck! of taken along the I a lower section 3; downwardmovement of the upper section into the lower section being limited by anoutstanding head 4 which rests on the upper edge of the neck 2. Casters5 are provided for the lower section at its corners in order that the 6conditioner may be readily moved from one room to another or from oneportion or a room to another in case it is-used in a large room. Theupper and lower sections .are formed oi. 'any materialdesired, althoughstrong sheet metal is 10 preferably used and walls of the lower sectionjare lined, as shown at 6, to strengthen the same and r by forming thisliner of rust-proof material, rusting and ,corroding of the lowersection will be prevented.

The upper section I is cylindrical in shape and of slightly lessdiameter than the lower section which is rectangular in cross sectionand this" upper section is open at its upper and lower ends but at itsupper end carries a head or cover 20 formed with a depending flangewhich fits tightly about the walls of the upper section so that a, tightjoint will be formed. The central portion of the head is cut out and thematerial of the head bent to vform an annular seat 8 into which 35.

is secured the upper end of a cylindrical sleeve 9. This sleeve orcylinder is 01 greater length than the upper section andwhen the uppersection is in place, the lower portion extends downwardly into theconverging portion III of the 30 lower section, as shown in Figure 2. Asthe upper end of the cylinder is firmly secured in the seat 01' the heador cover, this cylinder may be drawn outwardly by grasping the cover andexerting lifting movement. Between the cylinder and walls of the uppersection there have been arranged a plurality of baflles ,or deflectors Hwhich extend vertically, as shown in Figure 1, and are disposed radiallyof the cylinder and upper section, as shown in Figure 3. These bai- 40fies maybe formed of sheet metal bent to assume the desired shape, andreferring to Figure 1 it will be seen that each baflle has diagonally.extending portions I 2 which are disposed at right angles to each other.It should be further noted 45 that one end or each of the diagonallyextending portions has been extended to form a lip l3. By thisarrangement, tortuous passages will be defined between the bafiles andas air passes up-' wardly between these bailles, moisture in the 'air 50'will be deposited upon'the lips and diagonally a motor 14 which isdisposed vertically in the cylinder axially thereof and to theprojecting lower end of the motor shaft is firmlysecured a fan I5. Themotor is supported in the sleeve or cylinder bya yoke l6 having itsbridge 11 extending diametrically through the sleeve and its arms. l8extending upwardly from the bridge against walls of the sleeve. Inspaced relation to the bridge the arms are bent toward each other, asshown at I9, and then upwardly to provide portions which are securedagainst the motor by bolts 2i, and above the motor the .arms are againbent to form flaring portions 22,

the upper ends of which are again bent'to form feet 23 overlying theseat 8. Through the seat are passed bolts or rivets which firmly securethemupon the bead, and'in order to prevent rattling noises, rubber pads24 are tween the seat and feet. i

The yoke not only serves as a carrier for the motor, but also as asupport for a shaft 25 which extends axially through the sleeve 9 withits upper end rotatably received in a bearing 26 formed midway the widthof the bridge I! of the yoke. The upper end of the shaft is connectedwith the lower end of the motor shaft 21 by a flexible providedbeconnection 28 formed of rubber tubing or any other suitable materialand firmly secured about the two shafts by clamps 29. .The lower end ofthe shaft 25, which may be referred to as a pump shaft or sprayer shaft,is journaled in a bearing 30 which fits into an opening formed in thehub of a spider 3i, and referring to Figures 2 and 5v it will be seenthat the spider is disposed in .bridging relation to an opening formedat the center of the bottom of the lower section. Be-

neath this opening is mounted a sump 32 in which dirt is to collect andin order to hold the spider in its proper position the legs of thespider are equipped with depending arms or brackets '33 carrying rubberpads 34 which frictionally engage walls ofthe sump. There have also beenprovided pads 35' upon the legs of the spider which rest upon the bottomof the lower section.

By this arrangement the spider will be firmly held water is necessarybefore the lower section of the conditioner needs to be cleaned. Thiswatermay be of any depth desired from the bottom of the lower section tothe opening but is preferably of the depth indicated in Figure 2.

This water is to be sprayed upwardly and form a fog through which airpasses and in order to do so there has'been provided a pump or sprayer38 carried by the shaft 25. This sprayer is of conical shape and hasinner and outer walls 33 and 40, the upper edges of which are joined byan annular wall 4! having openings 42 formed through the outlet as cleanand cooled air. As.

therein. The shaft extends through a sleeve 43 which is axially alinedwith the apex of the sprayer and at the top of the sprayer therehas theshaft 25 by a pin 46. It willthus be seen the temperature of the air.

manent location.

that the sprayer will be firmly secured to the shaft to rotatetherewith. The lower end portion of the sprayer is immersed in the waterand when the shaft and sprayer are rotated, water will pass throughopenings 41 formed about the apex of the outer wall and centrifugalforce will cause this water to move upwardly through the space betweenthe walls of the sprayer to the upper end thereof where it will bedischarged as a spray through the openings 42 in the marginalwalls M.The fact that the'sprayer is rotating at a rapid rate of speed willcause the sprayed water to be thrown upwardly and outwardlyas very finewater drops thus forming a thick fog which fills the lower section ofthe air conditioner. During this operation the fan draws air inwardlythrough the sleeve or cylindrical column 3 and forces. the airdownwardly through the sleeve to the open lower or inner end thereofwhere it passes into the lower section of the air conditioner. Uponentering causes dust and other foreign substances to be taken up by thewater drops andv also reduce During upward movement of the air about thesleeve 3 it passes through the tortuous passages. between the baffles iiand moisture will be deposited upon the lips and end portions of thesebailies. It will thus be seen that the water fog will be confined withinthe air conditioner and the water which will accumulate upon the baiiiesand walls of the upper and lower sections will flow back into the bottomof the lower section where dirt will gravitate through the water to thebottom of the lower section and into the sump. The bailes terminate inspaced relation to the upper end of the upper section I, and above thebaiiles the upper section is formed with an outlet opening surrounded bya collar or neck 43. Blades or I louvers 49 are pivotally mounted in theneck 48, as shown in Figures 2-and 3, and inner end portions of theblades carry arms or brackets 49. pivoted to a cross bar or strip .50 tocause the blades to move simultaneously about their pivots whenreciprocating motion is imparted to the cross bar by a. link IIextending from the outer end of a lever 52. This lever is pivoted upon ahanger 53 and'has a fork I4 at its inner end engaging the eccentric pinll of a gear Bl meshing with a. small pinion 51 carried by the shaft ofthe motor and, therefore, the lever will be rocked about the hanger as apivot to impart oscillating movement to the blades when the conditioneris in use. Since thue blades swing about their pivots of the outlet neckor mouth 48, air which passes out through this mouth will be directedtoward different 'portions of a room as the blades move. .It will thusbe seen that warm and dusty air in a room may be drawn into theconditioner where it is passed through a water fog to remove dust andreduce its temperature and then returned to the room the device isprovided with it may be very easily moved from one of a large room toanother or transferred from one room to en'- other. It will be obviousthat an air condition constructed in accordance with this disclosure maybe erected as an immovable device in a per- 'lower end spaced from thebottom of the casing,

a yoke in the sleeve having a bridge extending transversely across thesleeve and arms extending upwardly through the sleeve against wallsthereof, the arms having their upper portions bent to converge upwardlyand being then extended upwardly in spaced parallel relation to eachother and then bent to diverge upwardly and having their upper endssecured at the top of the sleeve, a motor secured between the spacedparallel portions of the arms of said yoke in a vertical position withits shaft disposed axially of the sleeve, a fan carried by the motorshaft for drawing air inwardly through the inlet and forcing the airthrough the sleeve into the lower portion of the casing for passageupwardly about the sleeve to the outlet, a bearing at the bottom of thecasing, a sprayer shaft disposed vertically with its lower end mountedin the bearing and its upper portion bridge of the yoke and connectedwith the shaft of the motor to rotate therewith, a sprayer carried bythe sprayer shaft for spraying water upwardly in the casing and forminga water fog through which the air passes, the motor, fan,

journaled through the tion from said motor, and an sprayer shaft andsprayer being removable upwardly through the sleeve with the yoke as aunit, and means about the sleeve for extracting water from air passingupwardly about the sleeve, to the outlet.

2. An air conditioner comprising a casing having an air inlet at its topand an outlet in its upper portion, a sleeve leading from the inlet andhaving its lower end spaced from the bottom of the casing, means forpassing air through the inlet and sleeve into the lower portion of thecasing including a motor mounted vertically in the sleeve, a sprayer inthe lower portion of the casing for spraying water and forming a waterfog through which the air passes, means for extracting water from air asthe air passes upwardly about the sleeve toward the air outlet, bladesin the air outlet spaced from each other and movably mounted fordirecting discharge of air from the outlet, the blades being connected,

for simultaneous movement, and means for imparting movement to saidblades including a bar pivotally mounted for oscillating movement andhaving one end portion extending into the sleeve transversely thereofand formed with forks, a gear rotatably mounted and receiving rotarymoeccentric pin carried by said gear and engaged between forks of theshaft for imparting oscillating movement thereto as the gear rotates.
